列表视图不会在详细信息视图中呈现项目

Question

VariableBox = gcnew ListView();
VariableBox->Font = ScriptEditorOptions->FontSelection->Font;
VariableBox->Dock = DockStyle::Fill;
VariableBox->BorderStyle = BorderStyle::Fixed3D;
VariableBox->BackColor = ScriptEditorOptions->BCDialog->Color;
VariableBox->ForeColor = ScriptEditorOptions->FCDialog->Color;
VariableBox->DoubleClick += gcnew EventHandler(this, &ScriptEditor::VariableBox_DoubleClick);   
VariableBox->View = View::Details;
VariableBox->MultiSelect = false;
VariableBox->CheckBoxes = false;
VariableBox->FullRowSelect = true;
VariableBox->HideSelection = false;
VariableBox->Tag = (int)1;

ColumnHeader^ VariableBoxName = gcnew ColumnHeader();
VariableBoxName->Text = "Variable Name";
VariableBoxName->Width = 70;
ColumnHeader^ VariableBoxType = gcnew ColumnHeader();
VariableBoxType->Text = "Type";
VariableBoxType->Width = 50;
ColumnHeader^ VariableBoxIndex = gcnew ColumnHeader();
VariableBoxIndex->Text = "Index";
VariableBoxIndex->Width = 50;
VariableBox->Columns->Add(VariableBoxName);
VariableBox->Columns->Add(VariableBoxType);
VariableBox->Columns->Add(VariableBoxIndex);
VariableBox->ColumnClick += gcnew ColumnClickEventHandler(this, &ScriptEditor::VariableBox_ColumnClick);

我在 WinForms 应用程序中有上述代码。控件直接添加到主窗体中。出于某种原因，当布局设置为 Details 时，它永远不会呈现任何项目或列 - 只有滚动条可见。以下代码用于将项目添加到其集合中：

ListViewItem^ Item = gcnew ListViewItem("Qw");
Item->SubItems->Add("Int");
Item->SubItems->Add("10");
VariableBox->Items->Add(Item);  

切换到任何其他视图（在运行时或设计时）可以解决此问题。关于为什么会发生这种情况的任何想法？

编辑：撞！还是不允许？

原来我在控件显示之前删除了列标题。
